SOIL TESTING SERVICES

GGPL provides Geotechnical services includingin-situ Geotechnical field investigations and laboratory testing. The in-house Soil Testing services laboratory caters todetermination of various geotechnical parameters as per relevant IS Codes.

GGPL also offers services for ground improvement/slope protection work. The ground improvement/ slope protection work is performed either for natural landslide or manmade vertical/ steep excavation for underground basement work, where there is no space for excavation in stabilized slope. Such services are performed using appropriate techniques like Soil/Rock Nailing, Piling, Shotcreting and Grouting.

The details of services offered are as follows:

1. Geotechnical Field Investigations/ Soil Testing Services

• Soil boring of 65 mm to 600 mm diameter borehole
